This paper analyzes the existing support methods and their working principles in Si ergoumen Gold Mine, uses the FLAC3D software to establish a roadway graded support mathematical model in conjunction with RQ value, the support grade index. Based on the quantitative analysis of the supporting parameters and supporting effects of various types of roadways, it developed the graded support standard for the roadway of Si ergoumen Gold Mine, which provides the basis for choosing optimal supporting scheme for various types of roadways.
